2 Claims.

The invention has relation to means for transferring a total accumulatedin oneaccumulator into another or grand total accumulator, and itconsists in the novel construction and combination of parts as set forthin the appended claims.

The invention is shown as applied to a listing calculator of the wellknown Gardner construction, illustrated in U. S. July 12, 1932 to ClydeGardner, deceased; as modified by the disclosure of U. S. Patent1,915,296, issued June 27, 1933 to Loring P. Crosman, and by thedisclosure of co-pending application Serial No. 10,270 filed by LoringP. Crosman of even date herewith.

Fig. 9 is a detail right side elevation of parts omitted from Fig. 3.

In the machine illustrated, amounts set up on the digit keyboard 2 I 5(Figs. 1 and 2) are accumulated in one or in bothaccumulators- 413,either additively by engagement of an accumulator during the upwardstroke or subtractively by engagement thereof during the downward strokeof reciprocatory actuating segments 6 I 0. The segments are reciprocatedby movement of a rock shaft 30I, preferably driven by electric motorI00, said rock shaft having a cam 3I8, adapted to move a rocking frameBIG, and thereby cooperating with the springs of the segments to effectmovement thereof. The extent of movement of each seg-.

ment is limited by engagement of a stop bar 6I5 carried by the segment,with the lower end of a depressed key 2I5, whereby this extent ofmovement will'correspond to the value of such depressed key. Type barsSII are connected with h egments 6I0, and are raised thereby to Patent1,867,002, issued 1935, Serial No. 10,271

bring the appropriate type to the printing line. Before the return ofthe adjusted segments by the' frame GIG, spring type hammers H5 will bereleased by triggers 70 I to print the item on a record sheet.

Plus and non-add setting The accumulators 413 are set to give thedesired registration by means of two cam plates MS, "I (Fig. 3) pivotedin the frame at 420 and 422, respectively, these plates cooperating withcams carried on the shafts 403 of the accumulators. From the positionillustrated in Fig. 3, the cam plates 4I9, 42I are rocked toward eachother by means of a rocker device 325, (Figs. 4and 6) connected with thecam plates by members 322, 32I, and operated by cam arms 320, 3 I 6,fixed upon the rock shaft 30 I. Rocker device 325, as set for normaloperation, provides for movement of plates 4| 9, 42I toward each other,as soon as the machine is put in operation, and before the movement ofsegments 6I0. At the beginning of the return movement of shaft 30 I,rocker 325 will be operated in a reverse direction, to return the camplates 4| 9, 42I to the position illustrated in Fig. 3 before the returnmovement of segments 6I0 is begun. Each of the cam plates 4I9, 42i is'provided with two .cam faces, 452, 454, these cam faces being offsetfrom each other transversely, and lying in different circumferentialangular positions. In 30 the position illustrated in Fig.. 3, the camfaces 452 of the plates are opposite the shafts 403, Whereas, uponmovement of the plates by rocker 325, the cam faces 454 thereof will bebrought opposite the shafts 403. 3

Each shaft 403 is provided with a cam 453, lying in the plane of therelated cam face 452, and a cam 455, lying in the plane of the relatedcam face 454. The shafts 403. may be held in either of three rotatedpositions, whereby the, high 40 points of cams 453 or 455, or the lowpoints of both cams may be brought opposite the cam faces of the plates4I9, 42I.

The shafts 403 are urged by spring means (not shown) away from the,segments IiI0, suitable guides in the frame of the machine being engagedby said shafts. Thus, the shafts 403 will hold the accumulators 413 outof mesh with the segments 6I0 unless a cam face 452 or 454 is engaged bya cam 453 or 455, in which case the accumulator will be thrown into meshwith the segments.

It will be seen that the low point position of the cams 452, 454 providea non-add adjustment for the accumlator 413. To set the accumulators foraddition, the cams 453 are rotatedto active position in which theaccumulatorsw-ill stand in engagement with the segments 6|!) when themachine is at rest; will be allowed to drop out of mesh with thesegments as soon as the ma chine is put, in operation and will bereengaged with the segments at the beginning of the return strokethereof. It'may be noted that the upper accumulator is set for additionin Fig. 3, the lower accumulator being setfor non-add.

.These settings of the accumulators are controlled by a lever l (Figs. 1and '7). which, as shown, is set to a position indicated by the letter Aon a'display plate shown in Fig. 1. This designation shows that this Aor upper accumulator is. set for addition and that the lower or Baccumulator is left inactive, or in non-add position, during operationof the machine by the normal operation key H4.

I Total printing A total is taken by releasing the differential stopbars H5 and allowing them to rotate the accumulators subtractively untilsuitable pins on the accumulatorwheels contact with 0 stop members. Thiswill set'the total in the type 1 bars, and the hammers will be trippedto print normal position, the accumulator wheels being I the total. Thebars 6l5 are then reengaged with the oscillating frame and during thereturn stroke of said frame are moved rearwardly to disengaged from theracks before the return stroke is made, whereby the accumulator whichhas been totalized will stand at 0.

The machine is set for reverse or subtractive operation by contact ofthe total key lever 'with a pin 352 (Fig. 4) on rocker control plate326,

the total key thus holding the plate out of the path of clockwiserotation of the forwardpam follower, so that the accumulators will notbe disengaged at the beginning of the operation, by i the action of camarm"'32ll. On the return stroke of the parts, the forward ca'm follower,coacting with cam arm 320, will disengage the active accumulator fromthe segments. The described setting of plate 326 also disables the rearcam follower. At the end of the cycle of operation a pin 350 (Fig. 3)will contact with arm 322 and restore rocker 325. Depression of' thetotal trip the column latches 2 M (Fig. 2), through pin 263 and rocker221' (Fig. 3), but will also trip a latch 620, through operation of acontrol arm 62! pivotally connected to said latch. Latch 620 normallyengages a lug on total segment 618, preventing movement of said segment,under the influence of the total spring 68! Upon tripping of the latch,segment 6| 8 will operate a shaft having a spirally arranged row of pins65l (Fig.

2), acting to trip the latching dogs Bl1 successively from right to leftof the machine, the tripping of said dogs releasing the segments andalso releasing stop members 6l3, so that they will fall into the path ofthe 0 stops 451 on the accumulator wheels.

When this zeroizing operation has progressed to the left hand side ofthe machine, a rearwardly extending arm of the total segment 6I8 willcontact with a projection of a rod I30 (Fig. 3) connected at its otherend to a trigger I31, adapted to release latch I I2, and thereby engagea clutch connecting rock shaft 3! with motor I00. The

key 218 will not only of the segment levers. The hammers will now betripped, and upon rearward movement of frame GIG the-segments and totalstopswill be restored to normal position.

The total key is locked in depressed position by latch 223, and isreleased near the end of the cycle. of motor operation by engagement ofa finger of rock arm 321 (Fig. 3), driven by parts 324 and 3I6 (Fig. 6)above a click pawl 222 of latch striker 220, the, parts of the totalsetting mechanism being then restored to, normal position.

The mechanisms above set forth are all described in detail in thepatents and application hereinbefore referred to.

Transfer totals Provision is made whereby the setting of a T transfertotal lever 6| (Figs. 1- and-'7) will set mechanism into position to beoperated by the total key 218 whereby the lower or B accumulator will bethrown into add position during the 'total printing operation, so thatthe total cleared from accumulator "A and printed on the record sheetwill be accumulated as a grand total in B accumulator. v

Lever BI is fulcrumed on a shaft 62 and at its lower end contacts with apin carried on a crank arm 63 of said shaft, setting of the lever bycounter-clockwise movement from the position shown in Fig. '7 serving torock the shaft 62, against the tension of a spring 64. Shaft 62 is heldin rocked position by engagement of a pin of lever 6| with a cam slot 69of an interlock plate 65, pivoted at 66 in the framing, and providedwith a notched portion adapted to register with a pin 61 fixed in thecontrol lever I. If control lever -l is not located-in A" position, pin61 will not be opposite the notch of plate 65, and said plate willprevent the setting of transfer total lever 6|. The cam walls 68 of thenotch of plate also serve as a means for releasing lever (H from 'thelockingv action of cam slot 69. Thus. when it is desired to reset thecontrol lever, the transfer total lever is automatically restored toinactive position.

' In addition to the crank arm 63, shaft 62 is provided with .two arms10 and 1| (Fig. 3) on the right hand side of the machine. Rocking ofshaft 62 by lever GI will move the arm 10 from the position shown inFig. 3 into that illustrated in Fig. 4, in which position, a dog 12,carried by said arm will be positioned beneath a pin 13 in the total keylever.

With lever 6| set in active position, the depression of total key 218will,'through engagement of pin 13 with dog 12, rock arm 10, shaft 62and arm 1| into the position illustrated in Fig. 5. This movement willserve, through a link 14 to raise a hook 15, pivoted to a cam plate 16,into latching engagement with a pin 11 of the cam plate 9, so that theplates 16 and H9 are rigidly connected for operation in unison. Dog12,.which is connected with the arm 10 by a pivot and alsoby a spring18, serves to hold the hook 15 in engagement with pin 11 during thesubse- 1 and that before the return movement of this frame, with thesegments 6I0, plate 4I9 will berocked upwardly, into the position shownin Fig. 6. When hook 15 is engaged with pin 11, this upward movement ofplate 4I9 will raise the cam plate 16 therewith, bringing a cam portion19 thereof into engagement with a collar 80, fixed upon the shaft 403 ofthe lower accumulator, and forcing said accumulator into meshingengagement with the segments. The return of the segments to normalposition will, therefore, add the amount taken from the upperaccumulator, andset in the type bars 6| I, into the lower accumulator.The return movement of cam plate 4I9, near the end of the cycle ofoperation, and the ,release and restoration of total key 218, will allowplate 16 to return to the position illustrated in Fig. 4, under theinfluence of the springs 64 and 18.

1 Negative totals As set forth in detail in Patent 1,915,296,hereinbefore referred to, amounts accumulated in the higher orderaccumulator wheels, located to the left of the keyboard are transferredto the printing devices when a total is taken. If the total is negative,the complemental registration in the accumulator will include a 9 in theabove-mentioned left hand wheel, and movement of the related type barfrom 8 to 9 printing position is utilized to set the true negative totaldevices in operative position.

The method of converting the complement of a negative total, set in thetype bars, to the true negative total is as follows: 1

A set of stops I43 (Fig. 2), yieldably engaging the stop bars 6I5 arelocked in position as ad- J'usted thereby in accordance with thecomplemental registration and the segments 6I0 are restored idly tonormal position. The segments are now again released and will be stoppedby the stops I43, the accumulator'being meshed during this subtractivestroke of the segments, whereby the complement is subtracted from zero,giving a registration of the true negative total. The segments are againrestored idly to normal position by a cycle of operation of frame 6I6,and the stops I43 are released, so that a second zeroizing operationwill now transfer the true total to the type bars. The printing of thetotal, which normally occurs at the end of the first total settingoperation has in this case been delayed, and will occur after the truetotal is set.

In moving from 8 to 9 printing position, the extreme left hand type barreleases setting shaft I46 (Figs. 3 and 8) which will thereupon berocked counter-clockwise by a suitable spring. Rocking of shaft I46suspends the operation of the printing and normalizing devices in knownmanner.

The release of the total key from its latch 223 (Fig. 3) is prevented byan arm I50 connected by link I5I with arm I52 of setting shaft I46, armI50 being held in the rocked position of the shaft in engagement withpawl 222 mounted on the latch striker 220, so that said pawl may not beoperated to actuate the'striker so long as setting shaft I46 remains inrocked position. Total key 218 thus remaining latched in operativeposition, the subsequent operations will all be of a subtractive nature,and the column latches 2I4 will remain inactive.

The first operation of the totaling mechanism under the influence ofspring 6,8I has served to engage the motor clutch, for the purpose ofrestoring the segments, etc., and in order that a second cycle of themotor drive mechanism may be secured, in which the subtractive operationof the accumulator will occur, the clutch will be held in operativeposition as follows:

A latch arm I51 (Fig. 8) will be carried downward by shaft I46 out ofengagement with a latching pawl I58 mounted on a plate I59, pawl I58being held upward, to permit the disengagement, by a second latchingpawl I10. Plate I59 being released from the latch, will be drawn rear-.wardly by spring pressed member I60 (Fig. 3) and a lug of plate I59will engage the hook end of link I30 (now in its lower position)connected to the trigger I3I, holding this trigger out of latchingengagement with the clutch lever I06.

In order to lock the segment stop members (43 in the positions assumedduring the preliminary total taking, the plate I59 is provided with apivoted extension I63 (Figs. 3 and 8) which, in the rearward movement ofplate I59 is held under tension against the pin I64 mounted on one endof an intermediately fulcrumed lever I65.

The consequent relative movement of plate I59 and extension I63 willrelease latching pawl I53 from the restraint of the second latching pawlI10, the former pawl falling upon latch arm I51. The forward arm oflever I65 operates a locking bail I66, engaging serrations lever beingnormally operated by a double faced cam I61 secured to arm 3I6 ofoperating shaft 30I. As arm 3I6 moves forward rocking bail I66 isreleased, by the action of cam I61, while in the rearward movement ofarm 3I6 the cooperating roller of lever I65 will ride the upper face ofcam I61, whereby the locking ball is brought into contact with the stopsI43. This will be the operation of the parts during the first cycle ofmo tor operation, which restores the segments. As the rear end of leverI55 is lifted by cam I61, however, in the return movement of the parts.pin I64 will be lifted free of extension I63, and said extension willimmediatiely move under the pin. holding locking bail I66 in engagingposition. where it will remain during the subtractive stroke of thesecond cycle of motor operation, that is to say, while the segments movethe wheels subtractively from 0 registering position to the extentallowed by the stops I43. At the end of this stroke a pin I68 in arm 3I6will engage a seat I69 in extension its extension I63 forwardly, inwhich position the parts will be held by latching pawl I58, moving intoengagement with the shoulder of latch arm I51.

The true negative total being now registered in the accumulator, asecond totalizing operation, occurring on the final motor operationcycle and accomplished by the means hereinbefore described, will resultin the printing of the true negative total. The total latch iscontrolled to initiate this second totaling operation as follows:

It has been seen that, because of the negative condition of theaccumulator, the total key is held in depressed position, which,ordinarily, would result in the tripping of the total latch 620 1 at theend of the cycle of motor operation (first cycle) which serves torestore the segment levers 6I0. This tripping action would occur becausepin I32 in the latch-operating arm 62I (Fig. 3), held depressed by key218 and arm 229, is contacted by shoulder I33, as rocker cam 3I8 reofthe stops M3, the

I63 and will move plate I59 and stores push rod I35 to normal position,tripping pivoted upon an arm I12 of shaft III, said memher lyingnormally between rocker cam SH! and push rod I35. Shaft I'II is rigidwith plate I59, and, as said plate moves rearwardly at the end of thefirst total setting operation, pivoted member I13 will be carried out ofregister, with rocker cam 3I8, so that, upon the subsequent return ofsaid cam to normal position, push rod I35 will not be operated. Duringthe subtractive cycle of operation, however, plate I59, being restoredto normal position by-pin I68 and part I69, pivoted member I'I3 will berestored to position beneath rocker cam 3I8, and at the end of thiscycle the push rod will rock plate I34 and trip the total latch.

This tripping movement of push rod I35 is utilized to restore settingshaft I to normal position. For this purpose shaft I46 isprevided withan arm I'I5.carrying the pawl I' I6 which, as shaft I46 is rockedforwardly is held-by spring I I1 in contact-with a shoulder IIll of pushrod I I35. As the rod is moved downwardly, pawl I16 and armI'I5will1rock the setting shaft back to normal position. Setting shaftI46 and the parts controlled thereby being restored to normal position;and total latch 620 being tripped, an ordinary total taking operationwill now occur.

Since the taking of a negative total will involve three reverseoperations of the rocker 325, the plate 4 I 9 will be moved at eachcycle of operation from the position shown in Fig. 5 to that illustratedin Fig. 6, and if the transfer total lever-6| is set to active positionat this time, three additive movements of the lower accumulator will beef- Iected. Near the end of each of these cycles of operation the plate9, in moving to its lower position-will contact with the stud of hook I5and move plate IS also into its lower position. During the first cycleof operation, the complemental registration taken from the upper or Aaccumulator will be added into the lower or "3 accumulator, and duringthe second cycle this same amount, which hasbeen locked in the stopmembers I43 will be added into B accumlator a second time. During thethird cycle, the .true negative total taken from A accumulator will beadded into Bf accumulator, the result being that, the two last namedoperations being complemental to each other, and thus cancelling out,the

complemental registration which originally stood in A accumulator willbe correctly transferred to the B accumulator. This may be betterunderstood from the following example:

Q i A accumulator "B accumulator method illustrated in the followingexample:

comprises the true negative total.
